Sub-orbital spaceflight — A sub orbital spaceflight (or sub orbital flight) is a spaceflight in which the spacecraft reaches space, but its trajectory intersects the atmosphere or surface of the gravitating body from which it was launched, so that it does not complete one … Wikipedia

Vol sub-orbital — Vol suborbital Un vol suborbital est la trajectoire d un engin spatial se déplaçant à une vitesse suborbitale, inférieure à la vitesse requise pour qu il se maintienne en orbite. Le premier vol suborbital américain eut lieu le 5 mai 1961, avec l… … Wikipédia en Français
Orbital spaceflight — Discovery rockets to orbital velocity, seen here just after booster separation An orbital spaceflight (or orbital flight) is a spaceflight in which a spacecraft is placed on a trajectory where it could remain in space for at least one orbit. To… … Wikipedia
Orbital mechanics — A satellite orbiting the earth has a tangential velocity and an inward acceleration. Orbital mechanics or astrodynamics is the application of ballistics and celestial mechanics to the practical problems concerning the motion of rockets and other… … Wikipedia
Orbital period — For the music album, see Orbital Period (album). The orbital period is the time taken for a given object to make one complete orbit about another object. When mentioned without further qualification in astronomy this refers to the sidereal period … Wikipedia
Orbital speed — Not to be confused with Escape Velocity. The orbital speed of a body, generally a planet, a natural satellite, an artificial satellite, or a multiple star, is the speed at which it orbits around the barycenter of a system, usually around a more… … Wikipedia
Orbital elements — are the parameters required to uniquely identify a specific orbit. In celestial mechanics these elements are generally considered in classical two body systems, where a Kepler orbit is used (derived from Newton s laws of motion and Newton s law… … Wikipedia
Orbital inclination change — is an orbital maneuver aimed at changing the inclination of an orbiting body s orbit. This maneuver is also known as an orbital plane change as the plane of the orbit is tipped. This maneuver requires a change in the orbital velocity vector… … Wikipedia
Orbital state vectors — In astrodynamics or celestial dynamics orbital state vectors (sometimes state vectors) are vectors of position ( ) and velocity ( ) that together with their time (epoch) ( ) uniquely determine the state of an orbiting body. State vectors are… … Wikipedia
Orbital station-keeping — In astrodynamics orbital station keeping is a term used to describe the orbital maneuvers made by thruster burns that are needed to keep a spacecraft in a particular assigned orbit. For many Earth satellites the effects of the non Keplerian… … Wikipedia
